00:16	pdurbin	:)
00:17	pdurbin	aditsu: you're still shell-shocked from your Haskell experience. PTSD :)
00:24	aditsu	it wasn't quite that bad, this article [series] is shocking enough by itself
00:29	pdurbin	I haven't actually read it yet. It looked interesting. I was linked from the comments of https://dzone.com/articles/java-8-optional-whats-point
00:29	pdurbin	wow. new people
00:29	sfisque	reminds me of a conversation with a "former smalltalker" who hated the necessity of testing for "null"
00:29	* pdurbin	waves at silencecm and stevejhonson
00:30	pdurbin	sfisque: are you using Optional yet?
00:31	sfisque	not yet. my feeling is optional is more SDK / framework level. as a mathematician, i have no complaint with null and nullity.
00:32	aditsu	it seems that I've used Optional a few times, for the sole reason that it made the code shorter and simpler
00:35	* pdurbin	didn't know sfisque was a mathematician
00:35	pdurbin	who knew that Optional was a monad
00:36	sfisque	who knew what a monad is before reading that (not this developer)
00:36	aditsu	I still don't know ^_^
00:36	pdurbin	as I was saying at http://irclog.greptilian.com/sourcefu/2016-04-22 I went to a talk yesterday that featured monads prominently: https://blogs.janestreet.com/incrementality-and-the-web/
00:36	aditsu	and it kinda makes me less (rather than more) interested in using Optional
00:38	pdurbin	I guess my takeaway is that Optional is supposed to be used when you're using functional programming features in Java 8.
00:38	pdurbin	and that it's easy to misuse Optional
00:39	pdurbin	before I use Optional I'll probably read the chapter on it in a book I have
00:39	pdurbin	searchbot: lucky java 8 in action
00:39	searchbot	pdurbin: https://www.manning.com/books/java-8-in-action
00:39	pdurbin	'cause I don't want to use it wrong

05:27	aditsu	speaking of books, this is awesome: http://dev.to/rly
07:32		sfisque joined ##friendlyjava
10:38	pdurbin	nice

16:03	aditsu	TIL a lesson the (very) hard way - if you use FXCollections.unmodifiableObservableList and add listeners to it, you have to keep a reference to the unmodifiable list (not just the original one), or else the listeners will be silently garbage collected
16:11	pdurbin	aditsu: what's you're favorite way to build GUIs? Wicket? JavaFX? Something else?
16:11		silencecm joined ##friendlyjava
16:14	aditsu	pdurbin: I prefer to make a distinction between (desktop) GUIs and web applications; if you're asking which of those I prefer.. I might go with web, but different projects have different needs
16:39	pdurbin	aditsu: ok, so if the choice is between web and desktop it sounds like you prefer making web GUIs. And if you are making a web GUI I assume you prefer Wicket. Is that right?
17:06	aditsu	pdurbin: basically, yes
17:07	pdurbin	ok
17:07	pdurbin	building GUIs is hard
17:20		Stooge joined ##friendlyjava
17:29	pdurbin	aditsu: are you tempted to check out any other frameworks for building GUIs? Either web or desktop?
19:51		silencecm joined ##friendlyjava
22:02	pdurbin	so I'm reading the chapter on Optional in Java 8 in Action and it says more or less the same thing as this blog post: http://www.oracle.com/technetwork/articles/java/java8-optional-2175753.html
22:03	pdurbin	https://github.com/java8/Java8InAction/blob/master/src/main/java/lambdasinaction/chap10/OptionalMain.java
